Item type:Publication, PRODUCTION RESULTS OF ALPINA GOATS FARM IN THE ZLETOVO REGION, NORTH MACEDONIA(Macedonian Journal of Animal Science, 2021); ; ; Ana PalaševskaThe role of goats in world livestock is significant and there is not a country in which they are not bred. The goat production in the Republic of North Macedonia is characterized by spontaneous and continuous development, and with each day there is greater interest of farmers for breeding goats as a business that provides secure existence and profit. The aim of the research within this study was to assess productive characteristics of conventional goat farm operating in the Zletovo region. The researches lasted 3 years (2008, 2009 and 2010) at the farm where around 100–120 heads of goats of all categories of the Alpine race are bred. Almost the whole milk produced at the farm is processed into dairy products such as: white brined cheese and cashkawall. The kids born there are used as kids for market of livestock products, kids sold as breeding goats and part of them are retained for own reproduction in the herd. The percentage of fertility was the highest in 2010 (125.32%), in 2009 was 122.99% and in 2008 was 118.99%. The percentage of conception was the higest in 2009 (90.63%), in 2008 was 87.78% and in 2010 was 82.29%.The average lactation length in 2008 was 258.3 days, in 2009 was 265.4 days, and in 2010 was 261.7 days. The average daily amount of milk production in 2008 was 0.93 liters, in 2009 was 0.96 liters, and in 2010 was 1.01 liters per head. The average milk yield in 2008 was 241.23 liters, in 2009 was 251.47 liters, and in 2010 was 263.57 liters. The farm worked with profit in all three years of research. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, PREDICTION OF TEST DAY MILK YIELD BY AC METHOD IN INDIGENOUS BALKAN GOATS IN MACEDONIA(Institute for Animal Husbandry, Belgrade-Zemun, 2017); ; Eftimova ElenaAccurate and precise milk recording is one of the most important moments for a successful selection of milking goats. In this context, breeders are constantly making efforts to find the most suitable and cheapest methods for conducting of tests for milk production. The goal of this research was to compare the A4 method (as referent method) with AC method (as alternative method), for determination of milk production, on the day of recording of the indigenous Balkan goat, in the period of 2014-2016 with milking of goats in the morning and evening. It was determined that the difference between the predicted daily milk yield with one milking (in the morning or evening) and the measured milk yield using the A4 method is too low and almost negligible. With the analysis of all factors (year, lactation and number of milk tests), it was determined that the prediction of total daily milk yield, based on the evening milking, provides more accurate result, in relation to the prediction during morning milking, in cases when using the AC method. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, CORRELATION BETWEEN CERTAIN EXTERIOR AND PRODUCTION TRAITS IN INDIGENOUS BALKAN GOAT IN MACEDONIA(Macedonian Journal of Animal Science, 2017); ; The purpose of this research was to determine the average values of certain exterior measures and production traits in goats of the indigenous Balkan breed in the Republic of Macedonia as well as to study their mutual correlation dependence. It was determined that the average body weight of the goats of Balkan breed is about 44 kg, whereas the values of the other exterior measures were: height of withers 65.40 cm, height of back 63.67 cm, height of sacrum 65 cm, body length 65 cm, chest width 21.73 cm, chest depth 25.23 cm, size of chest 82.40 cm, rump width 19.92 cm, rump length 23.05 cm. The average lactation was 166 litres. Regarding the strength of the correlation, the general conclusion is that there is a relatively weak correlation (0.2 ≤ R < 0.5) between most of the exterior measures. An average strong correlation (0.5 ≤ R < 0.8) was determined between the height of the sacrum and the height of withers and the height of the back, between the length of the body and body weight, as well as between the chest size and the width and length of rump. A strong correlation (0.8 ≤ R < 1) was determined between the height of withers and height of the back, as well as between the chest size and body weight. With the analysis of the correlative dependence of the lactation with the other exterior measures, it was determined that the lactation is not in correlation with most of the exterior measures, but there is an insignificant correlation (0 < R < 0.2) with part of them (height of sacrum, chest size and length of rump).
